It's not really about the fighter management side as that's a seperate entity and still requires work.

All depends what the overheads are and how much these members are paying. The could just pay a sign up fee type membership of £5 then for each class or they could pay £50 a month for all classes by direct debit for 12 months. Two very different membership styles.

If the gym was really doing well and a goldmine then the person running it would want it all to themselves and not share the massive profits on offer, in that regard it probably breaks even or a little more.

On that basis, I would like to make an offer of 0% of the value you are asking for, for 100% of the business ;-)

If you didn't see it with your own eyes, or hear it with your own ears, don't invent it with your small mind and share it with your big mouth!
